Otherwise you had already 51 points and the power to comment (and you can anyway - also with only 1 point - comment on answers to your questions and on your own answers). You can contact an administrator to merge your accounts. | |
| Oct 25, 2010 at 2:22 | comment | added | user10249 | Hmm... seems I can't comment yet, so I'll post my response here. To jp, thanks for a good idea. I have actually looked at something very similar using the paper "Extensions of G-posets and Quillen's Complex" by Segev and Webb (which refers to AS92). The poset X and Y in your poset don't seem to have homology which is easy to recognise, but there is an extension of Y which works much better. Still, I'm keen to understand Y as well. | |
